Um, I really don't know what you mean about the special menu.
I went through all the menus I could, from the system menu to the hotkey-tiggered in-game menu and everything displays in English.

The only thing I have noticed is that since Japanese is using unicode, games where there are accents like Pokémon will not display the é character but instead a Kanji. I assume it's because US games don't use Unicode (which makes sense because they don't need to) because if not the character would display properly.

Can you take a picture of what you mean? Maybe I forgot to add some files to the package.
